Wall decorative sheet adopting UPVC (unplasticized polyvinyl chloride) material

Abstract

The invention provides a wall decorative sheet adopting a UPVC (unplasticized polyvinyl chloride) material. The UPVC material adopts an LFUPV-001 type, the density of the material is 1.4g / cm<3>, the melt index of the material at the temperature of 390-400 DEG F is 215, the thermal distortion temperature is 70-74 DEG F under the pressure lower than 264 Pa, the oxidation index is 36%, the burning level is V-O / 5VA, the weather resistance level is F-1, and the burning speed index is RP-42; the UPVC material is prepared with an injection molding process, wherein the range of molding shrinkage is 0.2%-0.6%, the range of injection molding pressure is 60-150 mPa, the range of the injection molding temperature is 165-205 DEG F, the range of the mold temperature is 40-50 DEG F, and the injection molding speed is 20-50 cm<3> / min; the wall decorative sheet comprises bodies and fixing units, wherein the bodies adopt the UPVC material, can be detachably fixed on the wall and comprise first surfaces which face the wall and are matched with the shape of the wall; the fixing units are arranged on the bodies and used for fixing the bodies on the wall. The wall decorative sheet can be mounted on the wall conveniently, splicing and assembling can be finished conveniently, and the wall decorative sheet has the advantages of flame retardance, watertightness and environment protection and is easy to scrub and maintain.

Description

technical field [0001] The invention relates to a wall decoration board using UPVC material. Background technique [0002] In the decoration industry, the materials used in traditional wall interior decoration are mainly cement, mortar, ceramic tiles or chemical coatings and adhesives. With the development of the times, this decoration method has exposed more and more problems, which can be attributed to the following aspects: 1. Due to the complicated construction, the consumption of man-hours is high, resulting in high labor costs; 2. 1. Due to the long time for material preparation and construction, the construction period is long, which will be difficult for occasions (such as shops) that require frequent changes in decoration style; 3. Because the above-mentioned traditional boring does not fully consider environmental issues, it often contains harmful or Toxic substances (such as toxic gases such as polyoxymethylene), thus causing harm to the human body. 4. Decorativ...
